Papelbon had a meltdown and allowed four runs in the ninth inning for the blown save and loss on Sunday. He has converted 37 of 41 save chances, with a 2.10 ERA and a 0.90 WHIP over 64 1/3 innings. He will not appeal, leaving him eligible to return Sept. 23 in Miami.
Harper will likely be evaluated and the team should provide an update before Tuesday's game against Atlanta.
Ryu will not pitch Wednesday against the Rockies. Instead, he'll be shut down for at least four days before he is re-evaluated again. The team has not established a timetable for his return.
Hamilton has been sidelined since Sept. 4 because of a right shoulder injury. He batted .263 with 10 homers and 44 RBI over 335 at-bats.
"I think it's just a bump in the road," Ross told the San Diego Union-Tribune Saturday. "It could have been the 31st start. It could have been the third start. It was bound to happen and the key for me is to get a good night's rest, come to the park [Sunday] and start my process all over again and prepare for the next one."
Manager Bud Black said the Padres don't plan to limit Ross' workload over the final two weeks.
"It's good for Tyson to finish the season strong as he goes into the winter knowing that he's done it once he can do it again -- break 200 innings, make 33, 34 starts," Black said. "That means a lot to a pitcher as far as confidence and the mental edge that that brings, knowing that you can do that."
"That's why the breaking ball is better now," Soriano said.
Manager Matt Williams said the best-case scenario is for Soriano to regain closing duties, but he's not to that point yet. Drew Storen has filled in admirably so far.
"We're winning and that's what's most important,” Soriano said. "[Storen has] done it before and knows how to do it. It's a team and if you're not doing something consistently you have to put another guy in there to help. I don't have any issue with that, especially if we're winning."
Davis tested positive for amphetamines and began serving his suspension Sept. 12. Instructional league games begin Monday and end Oct. 7. Davis is eligible to return Oct. 14 -- or Game 4 of the ALCS, provided the Orioles advance that far.
